1.0 SCOPE
This specification describes the POWER LAN series of static uninterruptible power systems and presents its
electrical and mechanical features.
1.1 The system
An increasing number of machines are sensitive to disturbances on the mains power supply. The POWER
LAN series of static Uninterruptible power systems shall provide high quality AC power for electronic equip-
ment loads and shall offer the following features:
• Improvement in the power supply quality
• Compatibility with every type of load
• Protection against power failures
• Intelligent battery management
• Very low running costs.
The POWER LAN series offers Digital Interactive design architecture with minimum running costs.
Single-board digital technology now allows a high level of integration of components, allowing a reduced foot-
print and increased reliability (MTBF).
The use of latest technology power transistors, with switching times of 20 kHz, reduces circuit noise to
extremely low levels at any power rating, and ensures perfect output wave characteristics irrespective of the
type of loads being powered.
